Dear Mantainers,

I am having an issue with my ethernet card.
It works when the system boots but after around a couple of hours it disconnects.
I tried different ways to get it working without having to reboot but nothing else seemed to work.
Even rebooting doesn't solve the problem since again, after a couple of hours, it stops working again.
I have googled around and found that some people had this same problem on older kernels but no solution seemed to apply to this rc nor latest stable kernel versions.
I am probably missing something here.
The issue happened also with recent stable 6.1.7 and rc kernel versions.
I am actually testing the latest 6.2-rc4 version.

Following are some data I think might be useful but if you feel I neglected to give enough informations and you need more please just ask me.

Here some informations about my system :

I would love to provide a patch of any kind but I am afraid I don't have enough programming skills.

Thanks in advance for your time.

Dear Maintainers,

I am using this crude workaround daily and it seems to work (as per
upstream advice)

cat /etc/systemd/system/realtek-bug.service 
[Unit]
Description=Realtek Bugfix
After=network.target

[Service]
Type=oneshot
ExecStart=/usr/bin/bash -c '/usr/bin/echo 0 >
/sys/class/net/enp2s0/device/link/l1_1_aspm'
ExecStart=/usr/bin/sleep 1
ExecStart=/usr/bin/bash -c '/usr/bin/echo 0 >
/sys/class/net/enp2s0/device/link/l1_aspm'

[Install]
WantedBy=network.target

obviously each user has to find out the /sys path to his/her realtek
network device.
